Goodreads import books not working

I have been trying to import some ISBNs into goodreads for a number of days now but it has not been working. I constantly get the following message for hours. (Note that I am trying now to import one ISBN so the problem is not that the the file is too large.)

processing your imports...

(this could take awhile if your file is large)

Is there a problem with the import feature?

Thank you.
